Hacked, leaked, and held for ransom: The worst breaches of 2026 so far

2026 has seen several significant security incidents including a major breach affecting the Department of Government Efficiency (DOGE), compromises to critical energy and water infrastructure systems, and unauthorized access to an FBI surveillance system. These incidents represent a range of targets from government agencies to essential services infrastructure. The article highlights the most damaging breaches and incidents of the year to date.

Why it matters: Security practitioners need to assess exposure across federal agencies, critical infrastructure operators, and law enforcement systems, and review their own incident response protocols for comparable attack vectors targeting sensitive government and infrastructure assets.
